Observability in Cloud-Native Systems: Metrics, Logs, and Traces
How the three pillars of observability complement each other, and why having all three matters more than maximizing any single one.
Conceptual, architectural explainers — how a subsystem actually works underneath.
How the three pillars of observability complement each other, and why having all three matters more than maximizing any single one.
Where FreeDOS achieves genuine binary compatibility with MS-DOS, where it deliberately diverges, and what that means for running real DOS software.
How WSL2 differs fundamentally from WSL1's syscall translation, running an actual Linux kernel in a lightweight, tightly-integrated VM.
Why Terraform's state file is the actual source of truth behind every plan and apply, and how drift, locking, and idempotency all follow from that design.
How DOS exposes its entire system call interface through the software interrupt mechanism, with INT 21h as the single most important entry point.
How discretionary ACLs, mandatory integrity levels, and UAC's token-splitting combine to form Windows' layered access control model.
How the OCI runtime and image specs standardized what a 'container' actually is, and how containerd/CRI-O/runc fit together beneath Docker and Kubernetes.
The practical ways people actually run FreeDOS in 2026 — from firmware-flashing USB sticks to full virtual machines — and how to pick the right one.
How WinRM and PowerShell Remoting turn scattered single-machine administration into fleet-wide scripted management.
How admission controllers intercept API requests before they're persisted, and how OPA/Gatekeeper turn that hook into cluster-wide policy enforcement.
